With the correct parts and watching the video, it was so easy to repair. We ordered the wrong part (for the Electric Dryer when it should have been for the Residential Dryer) but the return was easy and we got the new parts super fast. Next time I would probably look at the offending part first before ordering just to make certain. But we used a socket set and Philips screwdriver and actually had our teens do all the work for experience. Fixed the loud noise one and for all.

Removed the back panel and saw that the idler pulley was worn out. It only took me 5min. To replace, it was very easy to replace.

I followed the repair Vedic and took the drum out and replaced the pulls and bracket. Very straightforward job. Dryer is now as quite as the first day we bought it.

Took off back of dryer Undid belt from belt adjuster pulled and took off adjuster put new one on redid belt and put back on dryer. Done

Simply followed the video that accompanied the part confirmation. Removed the top and front of the dryer. Removed the drum and belt. Unbolted (1 bolt) the Idler pulley and bracket and bolted on the new one. Reversed the sequence of disassembly and tried it out. The only minor difficulty was slipping the belt over the idler pulley after the drum was in place. This is where a second set of hands might be helpful to hold up the drum, while the other person puts the belt in place. Other than that, this was a simple repair and probably saved a couple hundred dollars for about 1.5 hours of my time. Thanks for the video...it was right on point, and made the job much easier.

Rather than remove the front panels, door, control panel and drum, I noticed 1/4" metal screws on the back panel. There were approximately 6 holding the back panel in place. I did have to remove the top panel as well before removing the back. Once removed I had complete access to the broken idler pulley assembly. I immediately saw the broken pulley. I installed the new one with very little effort. Reset the belt according to instructions from the video. Reassembled, plugged in, hit start and enjoyed the sweet sounds of success. All told it took me about 20 minutes from start to finish.
